Author

Mathis Petrovich

Usage

Import the functions

from hcy import rgb2hcy, hcy2rgb

Load an image (pixels have to be between 0 and 1)

import imageio
img = imageio.imread("lena.png") / 255.

Convert the image

hcy_img = rgb2hcy(img)
oimg = hcy2rgb(hcy_img)
assert np.max(np.abs(oimg - img)) < 10**(-13)
